WRENCH.

SPECIFICATIQN forming part of Letters Patent No. 310360, dated January 20, 1885.

.Application filed April 28, 1884. (No model) To all whom it may concern:

Be it known that I, JOHN L. PHILLIPs, a citizen of the United States, residing at Sullivan, in the County of Sullivan and State of -Indiana, have invented certain new and useful Improvernents in XVrenches; and I do declare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the acconpanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure l of the drawings is a vertical sectional view of my wrench. Fig. 2 is a side View. Fig. 3 is a crosssection View of the same.

This invention has relation to improvenents in wrenches for turning nuts and other analogous devices; and it consists in the construction and novel arrangenent of parts, as will be hereinafter more fully set t'orth, and particularly pointed out in the claims appended.

In the acconpanying drawings, A indicates the barrel or cylinder, which is made of metal or other suitable material, and gradually in creases in diameter from its rear to its forward end, where it terminatcs in a fiaring mouth, as shown at a. This barrel has its longitudinal sides L h flat and its longitudinal sides z' 'i roundcd or polygonal, the object being to prevent the clamping-jaws and their connecti ng cross-bar froni turning within the barrel or tube during operation.

B indicates the jaws, which are pivotally connected at their rear ends to the lateral arms of a centrally-threaded nut or cross-bar, b.

C indicates the handlawhich is preferably made of Wood, and made fast to the rear end of the barrel, as shown. The handle is perforated longitudinally for the passage of the threaded rod D, which engages the threaded perforation 'c of the cross-bar b. The handle is provided at its rear end with a plate, e, which is also perforated for the passage of the threaded rod D,to the end of which is secured by atransverse pin or other suitable means a turning-knob, I. The perforation plate e is secured to the rear end of the hauolle, and the rod D is shouldered adjacent to the inner face of said plate to prevent the rod from leaving the handle. The jaws B B are held apart at their forward ends by means of a flat spring, F. This spring is connected at its inner end to the inner plane face of one of the clamping-jaws, and is bent so as to have the opposite end engage the inner plane face ot' the opposite jaw.- These pivoted clanping-jaws are provided at their forward ends on their outer sides with rearwardly-inclined heads g, to engage the co rrespondingly beveled or inclined inner faces, Z, at the flaring mouth of the barrel A. By this Construction it will be perceived that when the operator turns the nut or knob I to the left the threaded rod D, through its en gageinent with the threaded cross-bar b, will drive the clamping-jaws forward from the mouth of the barrcl, while the spring will spread or press the jaws laterally until the outer sides of said jaws are brought in engage- 'ment with the inner plane sides,i 73,0f the barrel, thus causing the jaws to open as they are pressed forward.

To bring the jaws together, or reduce the space between them, the operator simply reverses the movement of the nut or knob I on the rod D.

It is not necessary that the entire forward nouth of the barrel or tube should be flaring or inclined ontwardly, as theinclinations may be applied only to the outer ends ofthe rounded or polygonal walls of the barrel.

Having thus described ny invention, what I claim as new, and dcsire to secure by Letters Palent, is

1. In a wrench the conbination, with the harrel increasiug in diameter forwardly to a flaring mouth, of the spring -jaws arranged ther-ein and pivotally connected at their rear ends by a cross bar, b, having a threaded aperture, said jaws having their forward ends headed and inclined 'earwardly on their outer 9 sides, and the threaded rod engaging the aperture of the cross-bar and provided at its outer ends with a turning-knob, substantally as specified.

2. The combination, with the barrel, constructed as described, of the pivoted springja-ws B B, the nut b, the handle C, the plate e, threaded rod D, and the knob for trning the threaded rod, substantially as specified.

In testimony whereoflaflix my signature in presence of two witnesses.
